Angled Bevel Circuit Board Edge Routing

Solution Overview

Problem

Existing methods for creating an angled bevel on a circuit board require an additional manufacturing step, increasing costs and complexity when mounting a straddle mount connector.

Innovation Solution

A circuit board with a bevel comprising an angled cut formed between the first and second surfaces, such that the first surface and the angled cut form an obtuse angle, and the second surface and the angled cut form an acute angle, eliminating the need for an extra manufacturing step.

VSEngineering Contradiction Analysis

1Reliability

If a traditional beveling process is used to create a V-shaped bevel on the circuit board edge, then proper alignment and reduced insertion forces for straddle mount connectors are achieved, but an additional manufacturing step is required, increasing cost and complexity

Engineering Contradiction:

Improveconnector alignmentVSAvoidmanufacturing process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the bevel formation operation with the existing edge routing operation by configuring the routing blade to engage the circuit board at an angle.
